b. To what extent can Singapore rely on exchange rate management and supply-side policies to address issues such as slow growth, income inequality, and declining trade. [15]
Introduction
Singapore faces economic challenges such as slow growth, income inequality, and a decline in trade, which require carefully formulated policy responses. Exchange rate policy and supply-side policies are two key macroeconomic tools that can be used to address these issues. Exchange rate policy influences trade competitiveness and inflation, while supply-side policies focus on improving productivity, labour mobility, and long-term economic efficiency. While an exchange rate policy can provide short-term stabilisation by managing inflation and external trade competitiveness, supply-side policies offer a more comprehensive long-term solution by enhancing Singapore’s productive capacity and addressing structural challenges such as income inequality and trade diversification.
Effectiveness of Exchange Rate Policy
Singapore’s managed float exchange rate system is primarily used to maintain price stability, as it helps manage imported inflation, demand-pull inflation, and cost-push inflation. Typically, the Monetary Authority of Singapore (MAS) adopts a policy of modest and gradual appreciation of the Singapore dollar (SGD) to control inflation. However, given current economic challenges, an alternative approach—such as a depreciation of the SGD—could be considered to boost export competitiveness and stimulate economic growth.
Depreciation of the SGD makes exports cheaper for foreign buyers, increasing demand for Singapore’s goods and services. This raises net exports (X-M), shifting aggregate demand (AD) to the right, leading to higher real national income through the multiplier effect.
As firms experience increased demand for their goods, they expand production and hire more workers, leading to lower cyclical unemployment and improved economic conditions.
Additionally, a stronger current account balance from increased exports could improve Singapore’s overall balance of payments (BOP).
However, depreciation also carries risks and may not be an effective long-term strategy:
Singapore is heavily reliant on imports for raw materials, food, and energy. A weaker SGD increases the cost of imported inputs, raising firms’ cost of production (COP), which could offset any gains in export competitiveness.
Higher import prices could lead to imported inflation, increasing business costs and reducing consumer purchasing power, particularly affecting lower-income households.
A zero percent appreciation (neutral exchange rate policy) could be a more balanced approach. This would prevent a stronger SGD from eroding export competitiveness while ensuring that inflationary pressures remain under control.
While exchange rate policy can help stabilise trade conditions and short-term economic fluctuations, it is not a sufficient solution for long-term challenges such as structural unemployment, productivity improvements, and income inequality.
Effectiveness of Supply-Side Policies
Supply-side policies focus on improving the efficiency, quality, and mobility of factors of production to promote long-term economic growth. These policies can directly address Singapore’s key economic challenges by increasing productivity, reducing income inequality, and enhancing trade competitiveness.
1. Boosting Economic Growth
Investment in labour productivity, such as subsidies for workforce training and skills upgrading, enhances the efficiency of workers, reducing firms’ cost of production (COP).
Lower production costs allow firms to offer more competitively priced exports, increasing net exports (X-M) and raising aggregate demand (AD), leading to higher economic growth.
Over time, improvements in labour productivity shift long-run aggregate supply (LRAS) to the right, increasing potential growth and ensuring sustained economic expansion.
2. Reducing Income Inequality
Supply-side policies that focus on skills training and education subsidies help lower-income workers acquire higher-value job opportunities, reducing wage disparities.
By increasing social mobility, these policies ensure that economic growth is more inclusive, preventing wealth concentration among higher-income groups.
3. Addressing Trade Challenges
Enhancing workforce productivity allows firms to transition into high-value industries such as technology, pharmaceuticals, and financial services, reducing dependence on traditional exports.
This diversification of exports reduces vulnerability to global trade disruptions and strengthens Singapore’s position as a competitive global trading hub.
Limitations of Supply-Side Policies
While supply-side policies offer long-term benefits, they have short-term limitations:
Time lag: Improvements in education, skills training, and infrastructure investments take years to yield substantial economic benefits.
Effectiveness depends on implementation: Not all training programs guarantee employment, and some workers may struggle to transition to new industries.
Conclusion
Both exchange rate policy and supply-side policies play a role in addressing Singapore’s economic challenges, but they differ in effectiveness over time. Exchange rate adjustments can provide short-term relief by stabilising trade competitiveness and inflation, but they have limitations due to Singapore’s import dependency and inflationary risks. In contrast, supply-side policies offer a more comprehensive long-term solution by enhancing labour productivity, reducing income inequality, and diversifying the economy. However, these policies require time to take effect and must be well-targeted to ensure their effectiveness. Ultimately, a combination of both policies—using exchange rate policy for short-term stabilisation and supply-side policies for long-term structural improvements—would be the most effective approach to ensuring Singapore’s sustainable economic growth.
